There is no integrated graphics on the P965 chipset. There is no integrated graphics on the NF570. Chipsets is the Northbridge that has the memory controller.
Dont get an Nvidia chipset for Intel, save yourself some trouble. Get the 965 chipset instead. Like the Gigabyte DS-3, or the ASUS P5B. You would want a better powersupply instead of using the one that came with the case.
